### What problem does this PR solve?
Issue Number: None
Related PR: None
Problem Summary: VARBINARY values in expression Fields are stored as
StringView, but create_texpr_literal_node<TYPE_VARBINARY> interpreted the input
pointer as std::string. When TopN pushdown builds a binary expression from a
VARBINARY runtime value, the StringView layout can be read as a std::string and
ASAN may report an oversized allocation while copying the literal. Read
VARBINARY literal data as StringView, preserve the exact byte payload when
creating TVarBinaryLiteral, and add coverage for embedded null bytes.
